A Hands-On Organ-Slicing Activity to Teach the Cross-Sectional Anatomy     

Lei Li  Lin Li  Yizhi Zuo 《Anatomical sciences education》2020,13(6):732-742

The presentation of pre-sliced specimens is a frequently used method in the laboratory teaching of cross-sectional anatomy. In the present study, a new teaching method based on a hands-on slicing activity was introduced into the teaching of brain, heart, and liver cross-sectional anatomy. A randomized, controlled trial was performed. A total of 182 third-year medical students were randomized into a control group taught with the prosection mode (pre-sliced organ viewing) and an experimental group taught with the dissection mode (hands-on organ slicing). These teaching methods were assessed by testing the students' knowledge of cross-sectional specimens and cross-sectional radiological images, and analyzing students' feedback. Using a specimen test on three organs (brain, heart, and liver), significant differences were observed in the mean scores of the control and experimental groups: for brain 59.6% (±14.2) vs. 70.1% (±15.5), (P < 0.001, Cohen's d = 0.17); for heart: 57.6% (±12.5) vs. 75.6% (±15.3), (P < 0.001, d = 0.30); and for liver: 60.4% (±14.5) vs. 81.7% (±14.2), (P < 0.001, d = 0.46). In a cross-sectional radiological image test, better performance was also found in the experimental group (P < 0.001). The mean scores of the control vs. experimental groups were as follows: for brain imaging 63.9% (±15.1) vs. 71.1% (±16.1); for heart imaging 64.7% (±14.5) vs. 75.2% (±15.5); and for liver imaging 61.1% (±15.5) vs. 81.2% (±14.6), respectively. The effect sizes (Cohen's d) were 0.05, 0.23, and 0.52, respectively. Students in the lower tertile benefited the most from the slicing experiences. Students' feedback was generally positive. Hands-on slicing activity can increase the effectiveness of anatomy teaching and increase students' ability to interpret radiological images.  相似文献

Academic personality and the commodification of academic texts     

Andrew Alexandra 《Ethics and Information Technology》2002,4(4):279-286

This paper explores the nature of, and justification for, copyright in academic texts in the light of recent developments in information technology, in particular the growth of electronic publication on the internet. Copyright, like other forms of property, is best thought of as a cluster of rights. A distinction is drawn within this cluster between first order `control rights' and higher order `commodity rights'. It is argued that copyright in academic texts is founded on its role as a means to allow academics to fulfil their role responsibilities. While the possession and exercise by academics of commodity rights can be thus justified in the case of mechanical print-based publication, since this helps make possible the reproduction and dissemination of academic texts, they cannot be so justified in the case of electronic publication. There are nevertheless good reasons to retain various control rights.  相似文献

Evaluation and publication delay in Ibero-American scientific journals     

Jon Zabala  Borja González-Albo  Ana García-García  Aurora Garrido-Domínguez  José Ignacio Vidal-Liy  Luis R. Álvarez-Díez  Soledad Hernando-Tundidor  Yara Mostazo-Fernández  Teresa Abejón 《Learned Publishing》2023,36(2):205-216

This article analyses the review, acceptance and publication dates of a sample of 21,890 articles from 326 Ibero-American scientific journals from all subject areas and countries included in the Latindex Catalogue 2.0 and published between 2018 and 2020 (freely available as an open access dataset). The aim is to discover evaluation and publication times. The evaluation process takes a median of 110 days, the publication process, a median of 82 days, and the whole process, a median of 224 days. Statistical differences are found according to periodicity, subject areas, countries, existence of a printed version and article type (Call for Papers or General articles). From the data we find that the delay in publication is longer than publishers themselves report to the DOAJ. STEM areas present the most similarity in publication patterns, having a higher number of evaluation days (Ed) than publication days (Pd); Arts and Humanities present the opposite pattern, with a higher Pd than Ed. In the case of Social Sciences, the times are similar. General articles and Call for Papers articles differ in terms of Ed, but not Pd, indicating that Call for Papers revisions are faster.  相似文献
